Humbie New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Humbie and across East Lothian. Fully insured, ARBOMaster approved and guaranteed for a year.
- Internal frame sealant that has split
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Don’t seal over failed sealant yourself
- Look at the sealant regularly in the first couple of years
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
About our new build mastic in Humbie
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. Typical jobs include cracks appearing as a new home settles and smeared, uneven beads picked up at snagging, across bathrooms & en suites, show homes and plot handovers.
Around smaller Scottish places like Humbie, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

When to call us in Humbie
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
It’s worth asking for a quote if you see:
- Kitchen sealant that has pulled off the wall
- Sealant that never bonded to the surface
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
Whether the job is in Humbie itself or nearby, the right material for each joint matters as much as a neat finish.
What to look for in a quote
- What product goes in the joint
- Whether all the old sealant comes out first
- What preparation is included
- What happens if they find a problem under the old sealant

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start.

- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.

Landlord and commercial work in Humbie
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
For anyone letting property in or around Humbie, several properties can go on one quote. Send us the addresses and the work at each.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
